    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

head gasket orientation

Can someone let me know which side of a head gasket is the top side?

The gasket has metal rings for each cylinder top which are flush on one
side and proud on the other. Is the flush side the top or the proud side?
 
For which model?

IIRC, the one I saw for a 16 valve 750 was marked "UP". So, you install it so "UP" reads correctly. If it's for another model, it may not have an up or down.

If you're not using an OEM gasket, you have my sympathy...
 
This is for a 1982 550.

As you guessed this is not an OEM gasket but I've
used OEM in the past and I vaguely recall a "TOP"
marking. I just can't remember which side was marked.

The OEM gasket had the spacer rings in it just like
the one I have now and I have a feeling the flush side
of the gasket mates which the head while the spacers
mate up against the piston sleeves.

Why not use an OEM? I'm curious to see how well the
cheap (NE) brand will work and I got time to do it over.
